The second person simply uses a terminal connection device to use the wireless WAN. For example, the global mobile communication system (G 〇 bal System jobile 〇) mmunicati〇ns ' GSM ) used by general mobile phones is a wireless wide area network connected by a GSM operator, and can provide high-speed resources. ^; ^ This is enough to support a wide range of data services, including fast Internet access, large file downloads, and streaming audio and video. The portable electronic devices of the control system are all widely equipped with an antenna system with an umbrella network. In general, the most common ones are based on the planar Inverted-F Antenna. However, in order to achieve better transmission efficiency, the structural changes are mostly oriented to the fine adjustment of the stereo j, which is complicated to manufacture. Ah, the height of the antenna is usually between two f meters. 'For increasingly smaller electronic devices, 'often it will make a rule,' especially for small-sized notebooks. [Invention] / According to this A wireless wide area network printed circuit disclosed in the invention has a relative surface and a first printed circuit board. 2 201014040 ϊ ϊ 与 与 与 与 与 与 与 与 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二 第二The feed source of the monopole antenna is fed, and then the first bandwidth and the second second bandwidth are operated by the ^11 monopole antenna and the second radiation monopole antenna. In the aspect of the 'feeding monopole antenna can also operate at a higher third bandwidth, the line length of the pole two is smaller than the second light-emitting monopole antenna, and the second radiation single is considered, and the second The second unipolar monopole antenna operates at: slightly MHz, feeds the monopole antenna and operates on the schematic 2〇〇〇MHz brush circuit. The narration is _·96_ζ and the 17th position on the details and technology of the present invention. The schema is illustrated below. [Embodiment] According to the invention, a printed circuit antenna of a wireless wide area network according to the present invention has a printed circuit antenna, a J circuit, 10, a feeding monopole antenna, and a first light. The monopole antenna π 2 and the second radiating monopole antenna 40, the printed circuit board 1 〇 includes an opposite first surface 11 (see FIG. 1 ) and a second surface 12 (see FIG. 1 ), in other words Just the two side surfaces of the printed circuit board 1 . The feeding monopole antenna 20, the first radiating monopole antenna 3〇, and the second radiating pole xenon wire 40 are all disposed on the same side of the printed circuit board 1,, as shown in the figure, fed into the monopole antenna 20, The first radiating monopole antenna 3〇 and the second radiating monopole antenna 40 are both disposed on the first surface u of the printed circuit board 1〇, and are fed into the monopole antenna 20, the first radiating monopole antenna 3〇, and the second radiation. The monopole antennas are not connected together. 201014040 The feed monopole antenna 20' is a conductive trace implanted on the surface of the printed circuit board - surface I], and includes a connected feed. The light conductor 22 is fed into the wire 21 For receiving the signal source, as usual, the coaxial cable (not shown) is soldered to the feed wire 21, and the apos is passed in, so that the line length of the feed wire 21 does not need to be too long, only It is enough for the coaxial cable to connect. The coupling wire 22 is configured to electromagnetically couple with the first radiation monopole day 30 and the two radiation monopole antenna 4 to excite the second Koda field monopole antenna 3〇 and the second radiation monopole antenna 4〇 The signal, therefore, the coupling wire 22 is generally elongated, the wire length is greater than the feed wire 21 to the feed wire 2, and the low first radiation monopole antenna 30 is a conductor wire that is implanted on the first surface 11 of the printed circuit board ( The conductive trace includes 'the front segment 31 and the rear segment 32. The line width of the front segment 31 is lower than the rear segment 32, and the first segment 31 of the first radiating monopole antenna 3 is closer to the coupling wire 22 fed to the monopole antenna 20 to obtain a comparison. Good electromagnetic consumption effect. In general, in order to reduce the size of the printed circuit board, the first radiating monopole antenna 30 is disposed on the left side and the upper left side of the first surface u of the printed circuit board 10, and can achieve a certain line length and can be printed. The length of the board 1不需要 does not need to be too long; and the line length of the first radiating monopole antenna 3〇 is substantially equal to a quarter wavelength of the first bandwidth it operates. The second radiating monopole antenna 40 is a conductive trace implanted on the first surface 11 of the printed circuit board 10. Similarly, in order to reduce the printed circuit board 10, the second radiating monopole antenna 4 The crucible is disposed on the right side and the upper right side of the first surface 11 of the printed circuit board 1 to achieve a certain line length, and the length of the printed electric board 10 does not need to be too long; and the second radiating monopole antenna 4〇 The line length is roughly equal to the quarter wavelength of the second bandwidth it operates. Please refer to FIG. 2, which is a schematic diagram of another embodiment of a printed circuit antenna of a wireless wide area network of the present invention.实际 When actually applied to an electronic device, the first radiating monopole antenna 30 and the second 201014040 radiating monopole antenna 40 need to be grounded to radiate signals, and therefore, the first radiating monopole antenna 30 and the second light emitting monopole antenna 4〇 The first copper foil 51 and the second copper foil 52 are respectively connected to the electronic device (not shown by t), and are connected to the electronic device. The ground plane is such that the first radiating monopole antenna 3A and the second radiating antenna antenna 40 are grounded. ❹
一方面，饋入單極天線20之耦合導線22亦可作為輻 射第三頻寬訊號之用，藉以達到足夠頻寬的目的。舉例來說: 藉由電磁耦合作用，使第一輻射單極天線3〇操作於 880-960MHZ的頻寬，而第二輻射單極天線4〇操作於 1650-1750MHZ頻寬，且最佳者為17〇〇MHz，配合饋入單極天 線20之耦合導線22操作於1950-2050MHZ的頻寬，且最佳者 2000MHz，而可使得整體印刷電路天線的工作頻 880-960MHz 以及 1710-2170MHz。 請同時參閱「第3圖」，其為本發明無線廣域網路之 電路天線之反射係數模擬示意圖。 根據上述第2圖之印刷電路天線之結構來加以模擬，d 圖中可以看出具有高頻（171〇_217〇MHz )盥 (880-960MHz)二個工作頻寬，換句話說，藉由第二輕射身 極，線3〇提供低躺1作頻寬，而第二輻射單極天線4〇與 入單極天線2G提供高躺I作頻寬，因此，第三頻寬高 二頻而第二頻寬又高於第—頻寬；根據_天線的基本々 概略等於四分之一波長，因此，饋入單極天線2( ，麵口導線22之線長短於第二輻射單極天線*的線長，妈 二輻射單極天線⑽的線長又短於第—輻射單極天線^ 的線長。 201014040 4A、4B圖」，為本發明無線廣域網路之印刷電路天線之調校後 反射係數量測示意圖。 藉由調整饋入單極天線20、第一輕射單極天線3〇以及第 二輻射單極天線40之各種相關數據：條件，譬如使饋入單極 20之稱合導線22的線寬小於第二輕射單極天線4〇，而 Ϊ二Ϊ射單極天線4G的線寬又祕第-輻射單極天線3。的線 二調縣合導線22的線寬為第二輻射單極天線4〇 半、第—輻射單極天線3G的前段31為第二輻射單 :供以二倍，而第一輻射單極天線30的後段32為 ^反射係各導線之麟義、距離等，而可獲得較 滅據與f知域，轉之平面倒F ^天線的三 種吊見先、樣之輻射效率比較表如下：On the one hand, the coupling conductor 22 fed to the monopole antenna 20 can also be used as a radiation third bandwidth signal for a sufficient bandwidth. For example: by electromagnetic coupling, the first radiating monopole antenna 3〇 operates at a bandwidth of 880-960 MHz, and the second radiating monopole antenna 4 〇 operates at a bandwidth of 1650-1750 MHz, and the best one is At 17 〇〇 MHz, the coupling conductor 22 fed into the monopole antenna 20 operates at a bandwidth of 1950-2050 MHz, and the optimum is 2000 MHz, so that the overall printed circuit antenna can operate at 880-960 MHz and 1710-2170 MHz.
